(Cl. 28-38) V Claims.

This invention relates to a compressor roll for a Warp compressor orother textile machine in which warp or yarn is wound upon a beam havingheads by rotation of the beam. It is the object of the invention toprovide such a compressor roll which shall be capable of adjustment toany length of beam, and it is the further object to provide such acompressor roll which shall be automatically and yieldingly extensibleso that its ends shall remain in contact with the beam heads during thewinding operation thus toextend over the entire length of the warp massand inwhich the cylindrical surface of the roll shall present nothing toindent or mar the warp.

These and other objects of the invention will appear mor fully from theaccompanying description and drawing and will be particularly pointedout in the claims.

The drawing illustrates a preferred embodiment of the invention.

In the drawing: Fig. 1 is a view in side elevation and partially incentral longitudinal cross section of a preferred form of the compressorroll with portions of the heads of a warp beam indicated atthe endsthereof;

Figs. 2 and 3 are details in cross section taken on the line 2-2 of Fig.1 and illustrating two :tions of a pin and co-operating bayonet slotforming preferred elements of the compressor roll.

Since broadly considered the function and operation of a warp compressorroll is well known and familiar to thoseskilled in the art, it will onlybe necessary here to describe the construction with which this inventionis particularly concerned, it being understood that the roll illustratedwill be made of the usual materials employed in such devices.

A warp beam comprises a central shaft and is provided at each end withdisk-like heads indicated fragmentarily at In in Fig. 1.

A preferred embodiment of the invention is illustrated in the drawing.Two important features of the invention are, first, that the compressorroll is constructed so that it may readily be adjusted to any requiredlength of warp beam, and, second, that it is constructed so that it willautomatically elongate upon a slight relative rotation of its sectionsto maintain its ends in contact with the inner surfaces of the beamheads and thus be in engagement with the entire width of the warp massduring the beaming operation. The first feature is important because itenables a single apparatus to be employed withany length of warp beamand the second feature is important because it insures that the pressureapplied to the warp mass during the beaming operation shall extend overthe entire width of the warp mass and thus insure uniformity throughoutthe entire warp mass and that there shall be no indentation or marringof the warp 'when extension takes place.

"In the preferred construction illustrated the compressor roll is ahollow cylinder and presents two main sections II and I2 havingco-operating end elements. In this case the end of the section I l isshouldered at 13 oppositely t0 the shouldered end I4 of the main sectionI2 so that these ends when brought. together co-operate and fitsmoothly. An auxiliary section I5 is provided having end elements, inthis case shouldered portions, to co-operate with the end elements ofthe main sections when interposed between the main sections, and in Fig.1 this auxiliary'section is illustrated as thus interposed.The'auxiliary section l5 may be of any desired length or more thanonemay be employed. Thus it will be seen that by interposing an auxiliarysection the compressor roll may be given any required length. Suitablemeans are provided for clamping together the two main'sections or forclamping the two main sections and the interposed auxiliary sectiontogether. In theconstruction illustrated spiders l6 and I! are mountedin and secured by rivets I8 to the main'section II and a spider I9 issimilarly mounted in and secured to the main section l3. A bolt having athreaded portion 20 is journaled at its shank 2! in the spiders l6 andI1 and held against inward movement by the head 23. A co-operating nutis formed in or secured to the spider i9. Thus by turning the bolt inthe nut the main sections of the compressor rollmay be clamped togetheror the main sections with the interposed auxiliary section may beclamped together. In the preferred construction the threaded portions ofthe bolt and nut are complementally mutilated to enable the bolt to heslid through the nut and then by partial rotation brought to clampingposition. This enables the sections of the compressor roll to be quicklyand firmly clamped together. For this purpose the nut comprises acylindrical portion 23 of the spider 19 with a section 24 pivoted at 25and with this section only provided with teeth 26, while the teeth ofthe bolt are omitted in a sector of the same width as the teeth 26. In

Fig. 3 the bolt is shown with the toothed portion 20 positioned with themutilated sector opposite the teeth 26 of the nut, thus enabling thebolt to be slid through the nut, while in Fig. 2 the bolt is shown withits toothed sector engaging the teeth of the nut to bring the parts intoclamping 7 position.

In the second feature of the compressor roll the hollow cylinder isformed to present two castellated complementary interengaging sectionsand at the right hand end of Fig. 1 the main secas 30, and extendsthrough and telescopes in a bearing 33 in the other spider, as 3|, and ahelical spring 34 on the stud 32 acts yieldingly to separate thecastellated sections and thus elongate the cylinder. In Fig. 1 thecastellated sections are shown closed but when the spring is free to actthe cylinder will be extended as indicated in dotted lines to pressagainst the face of the beam head ID.

A sleeve 35 interiorly telescopes both castellated sections and issecured to one of them, in this case by the rivet 36, to the outersection. A pin 3'! is mounted in the section free from the sleeve, inthis case the inner section, and extends into a bayonet slot 38 in thesleeve 35. The pin and bayonet slot co-operate so that when the sec-'tions are in contracted position the parts are in -the position shownin Fig. 5. In this position the compressor roll is brought between thebeam heads but when the beaming operation starts and the compressor rollrotates the spaces 29 permit slight relative rotation of the castellatedsections, the pin 31 is released from the notch of the bayonet slot andthe spring 34 then acts to elongate the compressor roll and cause itsends to engage the faces of the beam heads. The invention thus presentsa very simple and efficient compressor roll enabling a single roll totake care of any length of warp beam, and in suring the application ofthe required pressure to the entire Warp mass between the beam heads. fThis application is a division of applicants ap-v plication Ser. No.490,252 filed June 10, 1943, now Patent No. 2,337,129 dated December 21,1943.

Having thus described the invention, what is claimed as new and desiredto be secured by Letters Patent, is:

l. A compressor roll for engaging and compressing the warp as it iswound on a beam having heads at each end which comprises a hollowcylinder presenting two main sections having complementary end elements,an auxiliary section having end elements to co-operate with those of themain sections when interposed between the main sections, and meanslocated within the cylinder acting either to clamp together the two mainsections: or the two main sections and the interposed auxiliary section.

2. A compressor roll having the construction and operation defined inclaim 1 in which one of said main sections presents two castellatedcomplementary interengaging sections together with a resilient meanswithin the said main section acting to elongate the said main sectionthus to enable the said compressor roll to be adjusted to beams ofdifferent lengths and in each case to maintain its ends in contact withthe inner surfaces of the beam heads and thus the compressor roll inengagement with the entire width of the warp mass during the beamingoperation.

3.
